SPD-1 Source Code
I've had a few people ask about providing access to the source and design documents for SPD-1 so I've decided to make them available under GPL. A few people have built this controller from parts I've supplied. To help them I put together a short article describing the project. I've included a PDF version of this below. Please note that I do not supply parts or PCBs for this project. All of the source code is in MPLAB assembler and is intended for the 16C61/71 processor. Many of the source files are common to Neptune II so you may see references to that project in the source. To download the actual files simply right click on the links and choose "save target as".
